Application filed March 13, l1 922. Serial No. 548,222. i I

To all willem it -co/lwem: Be i vknown that JOHN LOGAN, a citizen v of the United States, and 'a resident ofthe considerably enlarged sheetof' fibrous material 5 such as rag felt vention, and having certain portions broken away to show more clearly the construction.

Fig. 2 is an enlarged cross-sectionalview taken along the line 2 2 of Fig. 1.

Fig. 3 is a fragmentary sectional View illustrating more clearly a lfeature 'of the invent-ion.

Fi 4 is a view of a porti/on of a roof showmg the eect produce-d byapplying. 4thereto strips of roofing specifically illustrated in Fig. 3.

Referring to the-dra`wings, the composite roofing forming the subject matter of this invention includes a relatively inexpensive or the like, whichJconstitutes the foundation or body portion of the roofing.

Th? sheet 5 may be impregnated with 'a suitable preserving compound such' as light asphalt, ythat is. an asphalt having a low melting point'. This tends `to resist the penetration of moisture into the felt anl thereby prevent the deterioration thereof.

One or both faces of the felt may be covered with a relatively thick coating or layers 6, '6 of impervious protect-ing compound, such as heavy asphalt or the like. These layers besides preventing the penetration of moisture into the fibrous sheet, v s

cut into shingle strips of any desired design.

Composite roofing constructed in accordance with this invention lpossesses distinct whether the latter be Wholly impregnated or dry, also tend to stil'en and strengthen the sheet and to become a substantial part of the body of the rooling.

One of the layers 6 has applied thereto relatively thin sheet of .metal veneer or surfacing material 7, such as copper or othermaterialnot susceptible to atmospheric conditlons.. l

The sald veneer Or surfacing materlal 1s vlik embodying features applied, preferably, to that portion of the rooting ordinarily exposed when the same is on a' roof orthe like, and is intended to protect the roofing from sparks, fire-brands and the like, as well as tolend'stability and Weatherre'sisting qualities to the roofing.

f The sheet 7 may be provided with a series of perforations 8 which maybe arranged in straight parallel lines extending transversely of the sheet, as shown, or may be arranged in any other designs to produce the desired eHect when the strip is laid on a roof or the e. The metal sheet may be imbedded in the adjacent layer of protecting'compound a` distance substantially equal to the thickness of the veneer, thereby bringing .its upper surface substantially flush with thehuncovered surface of the layer and, if the sheet be perforated, causing the` compound to be pressed mto the perforations in a manner to be exposed at the outer surface of the sheet.

The entrance of the compound into the perforations not only assist the adhesive qualities ofthe compound by anchoring the veneer securely thereto, but the exposure of the compound through the perforations,

which are of greater lineal dimension than `the narrow intermediate'connecting strips 9,

presents the appearance of a continuous line,

suggestive vof the space between adjacent edgesof ordinary shingles, as shown in Fig.

4', when the overlapping strips are laid onv a roof or the like. v v If desired the compound may be pressed through the perforations and beyond the outer surface of the sheet 7, Where it may be pressed-or permitted to cover the connecting strips 9, thereby actually forming a continuous line of compound at the surface of said sheet.'l l Y Obviously, the roofing embodying this invention may be made in long sheets to be handled in rolls asin the case of some preparedroofing at present in use or may be cut to form individual shingles, ormmay be superior to Ordii 'ar asphalt roofing in' that e protection, is lighter it provides better in weight and presents a more pleasing appearance when exposure to the weather has caused the metal to assume its natural colorings. v

In other words, it possesses all t-he advantages and ehminates the disadvantages o1 the ordinary asphalt rooting and the allmetal roofing.

It desired, the metal sheet 7 may be corrugated, crimped or embossed with various ornamental designs, ormay be oxidized or otherwise treated to produce the desired appearance.

Obviously, the invention is not limited 'to the particulanconstruction shown, but may be variously modified. Moreover, it is not indispensable that all the features of the invention be used conjointly as they may be used to advantage in variously different combinations and sub-combinations.'l

Having thus described my invention, I claim: l A'1. Rootingmaterial comprising, in combination, a sheet of felt, or the like, impregnated with light asphalt; a layer of heavy asphalt. on each side of said felt; and a relativelythin sheet of copper veneer covrering a portion of one of said layers and imbedded therein a distance substantially equal to thethickness of said veneer.

2. Roofing material comprising, in combination, a sheet o'f impregnated felt; lay'-,n

ers of impervious protecting compound covering opposite sides thereof; and a metal sheet covering a portlon of one of sald lay'- -ers and imbedded therein.

y 3. Booting material comprising, in combination, a sheet of impregnated felt; layers of impervious protecting compound covering opposite sides thereof; and a perforated metal sheet. covering a portion of one of said layers and imbedded therein.

l. Roofing material `4comprising, in combination, a sheet of impregnated fibrous material; layers of impervious protecting compound on opposite faces thereof; and a metallic sheet adjacent one of said layers, the said metallic sheet having perforations for exposing some of the compound therethrough.

5. Rooing material' comprising, in combination, sheet ot' material coated with a layer of heavy asphalt or the like and having the portion thereof, intended to be exposed.- covered with a thin copper sheet provided .witli a serie-:vof perforations for receiving therein some of the said asphalt.

dfRooting 'material comprising, in combination, a.tib1'ous 'body layer, a metal surface layer having perforations therein, and an adhesive betw n the two. l

T. Composite rooting comprising, in combination. a sheet of material coated with heavy asphalt; a surface lsheet of thin material unitedl therewith; and means associated with said surfacesheet whereby. designs are formed of* said asphalt'on said roofing.'

, 8. Roofing material compr'sing, in combination, a sheet of flexible material coated with heavy asphalt; and a. thin metallic sheet-,united therewith and having perforations adapted to form stencil-like designsby exposing the asphalt therethrough.

In testimony whereof, I have signed my name 'to this specification. f`
